Micro Irrigation is an approach that uses less water and applies that water for the root zones more
rationally for plant growth. Micro Irrigation systems have that added advantage of being suitable for
production of high value crops. It is an ideal solution at times of water stress, such as droughts which
are very common to dry zones in Sri Lanka.

Conventional irrigation system , such as channel irrigation systems tend to waste water as large quantities of water are supplied to the field more than the requirement. Most of it runs away without being used by the plants.

Micro irrigation system is an approach to irrigation which keeps the water demand for the minimum by supplying only the needed amount for the crops. This is a slow and regular application of water directly to the root zone of the plant through an economically designed pipes and low discharge emitters. There are several types of micro irrigation, but the far most common are sprinkling systems, drip systems, in line drip tubing.

Mini hydro is a type of renewable energy. Hydro electricity is one of the most prominent energy
sources in Sri Lanka. Mini Hydro is hydro power plant which generates less than 10MW. Mini
hydro is highly efficient and low cost in maintenance which has lead to its popularity around the
country.Mini hydro’s can be classified in to High head and Low Head depending on the height of
the water flow.
